Let’s make it official

Well, I like blogging so far. It has been nice being able to record down you thoughts and progress with your projects. As a present to myself, I have decided to take the next step and register a domain for my blog. WordPress made the whole process really easy and inexpensive at 17 dollars (considering…

More than dead

Remember how I said that I was going to replace the battery on the RTC and finish the clock? Well, that’s a no go. I went and bought some CR2032s today and wired it up to the RTC and nothing happened. The RTC chip is most likely fried during the prolonged circuit shortage. Now I…

Almost there

I finished with the time and date settings, so now I can focus on other random functions. I was originally thinking of adding a counter but I didn’t think it would be really useful as I did not have a buzzer on Ticki. After seeing a digital dice project on Hackaday, I thought it would…

Debugging

In the interesting of saving pins, I used a simple voltage divider to have three buttons read by one analog pin. This meant that debouncing is done entirely in the software. Since one the the buttons is for mode and the other two for adjustments, they require different levels of debounce. The coding I have…

Smooth sailing

I finally finished the hardware rework for Ticki and this time I was extra careful with all the soldering and testing. I still ran into some unknown problem with the apostrophe LED (I need it for the degree symbol when measuring temp), but that was fixed by nudging the solder pin a little (probably a…

Cold feet

Yesterday I desoldered the segmented display and the wires to the main board. Ticki is back to what it was a month ago, for better or for worse. Now that I have all the parts I need to finish the project (minus a way to wire the temp sensor), I am feeling a little nervous….

Break’s over

Back to class once again. The parts from spark fun is here (the replacement display and a temperature sensor). That means I will start disassembling Ticki, this time being extra careful with the wiring. Oh yeah, the RTC module is likely on its last leg battery wise. I was an idiot (still am probably) and…

Happy NEW YEAR!

2010, another year has passed us by. It was a great year filled with new experiences and ideas. Now that the new year is upon us, there are resolutions to be set and probably broken. Still, I wish to have some goals in mind. First, make/hack/mod new things, bigger things. Second, learn about website building,…

The sad news…

Remember how last week I thought I burnt out a LED in the display? Well, I managed to do that today. F*#@! I guess I will get to use that replacement display after all. Talk about a yo-yo day, up and down.

New ebook!

Instructables recently published my BarBot projects in their Arduino ebook! Since the ebook is going for $1.99 on iTunes, Instructables is offering me a one year Pro membership. Cool deal!

Winter break and Ticki

Now that the hardware for the clock is pretty much all done (the temperature sensor should be here soon), I have been mainly just working on the firmware. Part of the trouble with this project is timing of the processes. Because the LEDs are multiplexed, display functions have to be refreshed every 2ms or so….

FML… or maybe not

Why am I posting at 4 am you ask? So I finished the hardware aspect of the clock, nicknamed “Ticki”. I wrote a few lines to test out the display. One of the LED segments was out. #@%&!!!!!! I was in shock. Especially since all the soldering were done. I guess I learned a valuable…
